OF NEW YORK, N. Y., A CORPORATION OF SHUTTLE.

Application filed November 3, 1923.

This invention relates to improvements in shuttles, and, particularly, to shuttles used for weaving tape and other narrow fabrics.

One of the objects of our invention is to provide a shuttle having a tension device that will maintain a uniform tension on the thread after it leaves the bobbin, and which will reduce to a minimum Vthe possibility of breaking the same.

Another object of our invention is to provide a shuttle that will contain a larger amount of thread without increasing the size of the shuttle.

A further object of our invention is to provide a shuttle that will accomplish the foregoing objects with simplified means.

lith such objects in view, our invention consists in the construction and combination of parts as hereinafter described and claimed.

In the accompanying drawings,

v vReferring to the drawings in detail, 5 denotes, as a whole, our improved shuttle. Its base member 6, which is principally of wood, is formed with the. customary elongated ,guideway 7 on one side and the rack 8 `on the opposite side, with upper and lower plates 9 and 10, respectively. These plates are composed ott aluminum or vother suitable Serial No. 672,472.

or guard for the cop 14 carried by the bobbin 141. The side members 12 and 1B, in this instance, are made ot' aluminum, and, besides being made of light metal they are cored to further reduce their weight, but they may also be made of wood.

The side members 12 and 13 are each transversely divided into two parts, as clearly indicated in Fig. 1, the side member 13 being hinged, as at 13', so that the upper portion ot the arch may be opened and turned to one side to 'facilitate the insertion or removal of the bobbin. This feature together with the vertical stationary bobbin and our special tension device enables us to increase the capacity of the bobbin without increasing the size of the shuttle. rFhe side members are normally held securely together by a pin 15 working in a suitable keeper as at 16 in the side member 12, and having a lateral spring-pressed pin 16 working in a groove in the pin 15.

The bobbin 111 is held in relatively stationary position on a post 17, lixedly mounted in said base-plate 9 and having a spring pressed pin 18 working laterally in its sideto engage a corresponding groove on the interior surface of the bobbin, and the wettn thread 19 is drawn from the cop through a feeding ortension device, to be described, and out of the shuttle through the eye 20.

The tension device, designed by us with special reference to its use in connection with the vertical stationary bobbin, consists of a drag A `and a take-up device B, both located in the forward part of the arch.

The drag A consists of an immovable member C and a movable member D, sepaw rately shown in perspective in Figs. 5 and 6, the immovable member being iixedly mounted on a plate 21 fitted into- Igrooves 22 in the sides of the .arch .and removably held in place by spring-pressed pin 23. The immovable member C consists lor a thin strip of metal, having a straight portion 241 eX- tending partially across the interior oi the forward portion of .the arch and snugly litting against one of its sides,.and an angular portion 25, both parts being perpendicular to the plate 21 to which they are iiXedly at tached yby flange 26 `and rivets or other tastening means, as at 27.

The upper portion oft the same member is -secured against lateral Ymovement by {iange 28, into a suitable opening in which, and also in the arch, a pin or screw is inserted, as'at 29. The'immovable member C has horizontal cu't-a-way portions 30, extending substantially across the straight portion 24 and the angular portion 25 leaving bars 31, within which cut-a-way portions or slots 30, oscillate the lingers of the movable member D now to be described. Gn one of the bars 31 is an outwardly-extending pin 31 which cooperates with the angle of the lingers of the movablemember Dto keep the thread 1n a direct path to the eye 20. h

The movable member D likewise consists of a thin'strip of metal having cut-a-way portions 32, leaving fingers 33 adapted to oscillate, as before stated, between the bars 31 of the immovable member and to exert a -gentle drag upon theweft-thread carried by the bobbin and passing between the said bars and lingers. In order to adapt the fingers to perform this function properly, they are made, preferably, with backwardly bent portions or phalanges 34 androutwardly bent portions or Vphalanges 35, the latter acting as stops to limit one movement of the fingers.

The movable and immovable members are pivotally connected to each other by means of a Vpin 36v passing through suitable perforations in a downward extension 37 of the flange 28 on the immovable member C and ears 88 of the movable member D to a seat `in the plate 21.

Means are provided for causing the tingers 33 to yieldingly press upon the thread as it passes between them and the bars 31, to prevent the thread from being too freely drawny from 'the bobbin. This pressure means consists, preferably, first, of the spiral springs 39, one end of which is attached to the arm 40 extending from the body of the movable member D; second, a control rod or bridle 41 having one end pivotally .secured to the pin 42 fiXedly mounted in the plate 21, said bar having an eye, as at 43, with its loose end bent downwardly to make a set pin 44, which may be inserted in any of the series of perforations 45 in the plate 21. As

the spring 39 has its end opposite the arm 40 connected to the control rod or bridle 41, the force exerted by said spring, and, consequently the tension on the thread from the bobbin, through the fingers 33, may be increased or diminished at will by inserting the point of a lead-pencil or the like into the eye 43 of the control rod 41 and with the end of the pencil, placing the set-pin into the hole that will give the esired tension. The control rod or bridle 41 keeps the end of the spring to which Hit is attached in place and in the path of the perforations intended for the set-pin.

As is Well known, between the different movements of the shuttle, a certain amount of slackness in the thread occurs. live have provided for taking up this by a take-up device shown in Figs. 1, 2, 4, 7 and 8 ot the drawings. In a bracket 46 attached to the under side of the plate 21 is an outwardhr extending liXed pin 47, to the outei` end of which is pivotally connected the arm 4S. This arm 4S is elongated and curved, as shown in Fig. 4, its curve contm'mingl to the shape of the abutting plate 49 with which it co-operates and is next to be described. The arm 48 is controlled by a spiral spring 5U, which causes it to occupy the position shown in Figs. 1, 2 and 4, and at its loose end has a hook or eye 51 for holding the thread before passing out of the shuttle through the eye 20.

The plate 49 has a two-fold purpose. First, it limits the backward nioveinent of the arms 48 under the influence of the I# spring 50, thereby preventing the arm from coming in contact with the thread on the hobbin, and, secondly, its convex sides 52, as shown in Fig. 4, co-operates with similar sides of base-plate 9 to provide a guard for the thread on the bobbin when the shuttle is passing through the warp threads of the loom. The plate 49 is also provided with an annular opening 53 to allow full play for the thread as it is drawn from the periphery ol the cop held by the stationary bobbin. lhis annular opening in the plate 49 is clearly shown in Fig. 4. It will now be understood, therefore, how the arm 48 of the take-up device co-operates with the necessary features of the plate 49 in order to perform its own particular function.

The entire tension device carried by the plate 21 may be readily removed by first withdrawing the pin 20 and then thc plate 21.

In addition to the features of the plate 21 hereinbefore referred to, it has a small central opening, as at 54, through which the thread passes on its way from the bobbin to the tension device.

The course taken by the thread through the tension device is, preferably, a zigzag one, as clearly shown in Fig. 2 of the drawing, going, first, over the lower bar 31 then around one side ot the lower linger 98. then under the middlev bar 31 and one side of that bar, and so on, through the remaining lingers and bars. As the thread is thus drawirhetween the bars 31 and lingers 39, thc latter are vdrawn back against the action of spring 39 and caused to assume the position relatively to the bars shown in Fig. 9. Before, going through the outlet eye 20, the thread passes through the hook or eye 51 at the outer end of the arm 48. lVhcnever slackness of the thread occurs, the arm 4S in taking up this slack, under the influence of spring 50, assumes somewhat the position shown in Fig. 1. lVhen the thread is pulling from the bobbin the arm t8 under the influence of spring 50 takes the position shown in Fig. 7

lt will, therefore, be understood that the taire-up member B has a double function; for, besides acting to take up slack in the Wett thread, it (zo-operates with the member A in exerting a normal tension on the thread as itleaves the shuttle.

lt is obvious that the tension on the thread in passing through our improved tension device will bel uniform at all times, irrespective of the size ot the bobbin, or Whether it is full or nearly empty, and that, consequently, there is less liability ot breaking the thread. It is also obvious that we have largely increased the capacity of the shuttle with no increase in its size, due to our compact tension device and the fact that We can remove the upper part ot' the arch and mount therein a non-rotative bobbin completely filling the arch from side to side which would not be possible with a rotating bobbin.

1t will be evident that modifications may be made in the structure and arrangements oit the parts ot our device Without departing from the scope of our invention.
